Hankook RS-4
 

Just popped up on TR.
225/45/15 $127.81
245/40/15 $134.03
Interesting to note the tread depth of 8.9/32", because Chumpcar

Ordered the 245/40/15 to use on a 15x10. I'll be able to directly compare to a 225 RS3. I'm curious to hear results from my works chumpcar team, since they currently use 245 Maxxis VR1's on their E30 and they will be testing the RS4's.

Nice edit on the wheel pic, Emilio... ;)

i ordered a set of these for the exocet about a month ago, was told they would ship mid march. also going from 225 rs3 to these.

Good timing. Love my 205 RS-3's and almost time to change to 225"s

:rofl::rofl:

#stillmad

Ordered a set to replace the 245 VR-1s on Acamas, but I will do a single session on them in Rover to benchmark against the 245/40 RC-1 as well.

Please head up to Oroville and provide some wet feedback.

Our team love the ad808rs in the wet and dry, it'd be awesome if we could find a 225 that had better grip in the dry without sucking in the wet.

Nice price for the 245, especially when compared to the 245 Rival S at $171. Will be interesting to see how they stack up against the new BFGs and Nexens.

I'm still praying that they will wear like the RS-3s.

Same. At that price I have my hopes up. It would be awesome to have a true 200tw option instead of another Super200.

Oh man. $134 245s that last a season or 2 and dont wear out on the drive to MRLS. :love: If thats the case I think we have reached HPDE nirvana.

I am getting into a slight pickle with trying to determine which route I should go. Should I wait another few weeks for the RS4's to come in, or go ahead and get the Rival S? My first autox of the year is early March and track days soon to follow, so I would like to start out fresh. The car does see street time as well, and is currently on stock warped wheels with shitty tires. I can autox this setup but do not feel comfortable putting it on the track just yet. My 6UL's are in the mail so I will have them soon enough. Any advice on which tire I should go with?

I had the same dilemma because my first practice event is on 2/19 and I could not wait any longer for this or the 245 Rival S to show up. I decided to grab what was proven (Rival S in 225 on a 9" wheel) knowing I can always switch to something else if the inevitable testing shows vast improvement. Pretty safe to say driver mods will help me more than more tire so I'll probably just stick with that setup all season.

Bird in hand.

RS4 not likely to be > Rival-S. Equal? Maybe.

Very valid points, I was thinking more on the lines of best bang for the buck. This is my first year out on the track so I know I won't be breaking records or anything, would like something to last a while so I can spend more money on seat time than tires.

The Rival-S 1.5 dropped speed rating from W to V. That's really low. It indicates the tire doesn't shed heat as well as the original Rival-S. Fine for autocross. All the other 200tw's are rated W.
The sole 200tw's in 205/50/15 that are rated a lowly V, are the Rival-S 1.5 and RE71RVUp to 149 mphWUp to 168 mphYUp to 186 mphZ149 mph and over
Another interesting tidbit is the load rating. The Rival-s 1.5 jumps from LL (light load) 81 load index 51psi max to SL (standard load) 87 load index 44 max psi. I'd say that's an indication of significant changes to the casing and heat shedding ability of the tire. The 1.5 also gains 1lb over the previous Rival-S.

Neven Sur4 tread depth 9/32"
Rival-S 1.5 tread depth 7.2/32"

The potentially softer compound Nexen Sur4G due in the next month or two shares all the same specs as the current Sur4

I must have gotten lucky...ended up with a NOS set made last January that are 81W LL.

:party:

I think you are reading too much into this.

My understanding was that they needed to get certain load ratings for a couple of applications, so they just dropped the speed rating across the board. I can find out more, if you really care.

Nothing changed in "heat-shedding" ability, for sure.

The RS3 is a proven tire with a good track record. First year out tires will be the least of yor worries. A friend of mine who had no track experience, put baller R compounds on for his first year. In the first 30 minutes of his first track day, he had some Really expensive tires with Really bad flat spots. Because learning to drive...

Absolutely agree with you, I want to wait for the RS4 to come out just due to its longevity, but the release date is too close to the track day for my comfort. I think I'm going to give the Nexen SUR4's a whirl for now.

Thanks for the advice guys.

What magazine issue will tell us if they're equal-ish or not?!

Lap times?

fixt the original, heh.

I don't even have a set yet. So you will likely hear from others long before anything would appear in GRM.

Well shit... I took your "bird in hand" wayyy to literal.

Here's to hoping they'll be almost as fast as a super200 and last just as long as the RS3v2!

not likely.

what I meant was, go with the known quantity.

Just got an email that my RS4's have shipped. No tracking for ETA yet, though. They are coming from NV.

Ditto. Snoopy gets phat

We realize extreme ultra high performance for the FINAL WINNER.

Works for me.

Don't want to be the 2nd or third winner. Only the last.

Any initial impressions?

How do they smell?
Does the tread pattern look cool?
Taste good?

I am excited to have these mounted on the 15x9 advanti's I've had in a box for months

Is the rubber nice and stretchy? Any concerns about breakage during high friction situations?

Can we get durometer readings of RS4 vs. Maxxis trailer tire? I've been really happy with the wear rate of my Maxxis. Hoping the RS4 wears similarly.

Direct observation, controlled environment A/B data:

I walked out and dry humped the stack. Sonny said, "too late, I had firsties". So they tolerate sloppy second dry humping at least as well as Rival-S 1.5 225/45.

Anecdotally, durometer reading almost exactly the same as the tread on my new mountain bike shoes.

Jesus you guys are a bunch of ass holes, wouldn't have it any other way :rofl:

This information is much more relevant to my interests than anything in GRM.

:rofl:

Final winner makes me think of those dystopian movies where everyone is trying to win a lottery to go to some promised land, but in reality when they win they just get killed and their bodies recycled for food or organs.

Awaiting results on the Kao method of bead seating.

Got my set last night and scrambled them onto some 15x10s. At Thunderhill today. Did a back to back with a sticker 245/40 rc1 for a benchmark. The RS4 feels faster by a solid margin. Hard to say how much exactly because there's too much wind and traffic today but I'd estimate about a second or so faster. Lots more lateral and exit grip in particular. No odd wear patterns. I won't put enough time on them to know whether they wear like a super200 but they are definitely in that ballpark as far as speed goes.
​​​​​​

The one time I'm disappointed to see a tire have lots of grip. :mad: Fingers still crossed for magic wear but if it's that sticky I'm having doubts.

Jebus. Previous lack of 245 sized Super200's gave the RC1 a reason to be considered for 10's. That's out the window.

Sav,
Do the seem to run "wider" than labeled. To me the old RS3 always seemed more narrow than similar sized BFG-s. (at least in the 225).



(All these new tires an my car has been down since November with electrical problems grrrr)

Clearly I need to up my dry-hump game

We measured at the tread of the 245 RS4 exactly the same as the 245 RC1. The Nexen Sur4 on the other hand, is slightly wider than all the other tires except Hoosiers.

​​​​​​in for GRM new photoshoots.

Now I have to find a way to justify these to the "Chief Quartermaster" (aka my wife)...

Otherwise known as the CFO here

Holy crap! Do you think they will wear better than the RC-1?

um

yabbut how long wil they last

I mean one of them is a 40 treadwear, the other is 200. Can they be both be off by > a factor of 2?

Can't answer the question because it's based on a false premise (that treadwear ratings are linked to race tire life).

each session length? any overheating/drop off?

Fully expecting Super200 wear rates (aka nearly Hoosier wear rate and nearly same drop-off after 50% life). The future for those who want actual street tires isn't going to be in the 200tw category.

Yeah, I'm ok with that if they can take a 30 min. W2W beating.

My test data says 300tw PS4S and Conti Sport are where 200tw tires were five years ago.

Hell yeah! That means the Conti Sports will be a great replacement for my old RE11's then!
